冠状动脉痉挛是指心脏的一支或多支冠状转输动脉发生局部的或弥散性的暂时性收缩。冠状动脉痉挛不仅是变异型心绞痛的直接原因,而且也与急性心肌梗塞(AMI)心脏性猝死等病有密切的联系。因此,加深对冠状动脉痉挛的认识,有其重要意义。冠状动脉痉挛的临床表现一、变异型心绞痛与冠状动脉痉挛:据统计,住入冠心病监护系统的不稳定心绞痛病人中,变异型心绞痛约占20～30%。这类病人的临床表现是:①、心绞痛的性质与部位与典型心绞痛相似,疼痛发作一般在安静条件下,常见于后半夜至清晨,呈周期性的特点。②、心绞痛发作严重时,常并发严
Coronary artery spasm refers to the local or diffuse temporary contraction of one or more coronary transfusion arteries in the heart. Coronary artery spasm is not only the direct cause of variant angina pectoris, but also with sudden cardiac death and other diseases of acute myocardial infarction (AMI) are closely linked. Therefore, to deepen the understanding of coronary artery spasm, has its significance. Clinical manifestations of coronary artery spasm First, variant angina pectoris and coronary artery spasm: According to statistics, admitted to coronary heart disease monitoring system of unstable angina patients, variant angina accounts for about 20 to 30%. The clinical manifestations of such patients are: ①, the nature and location of angina similar to the typical angina pectoris, the onset of pain generally in quiet conditions, common in the middle of the night to early morning, showed periodic characteristics. ②, severe angina pectoris, often complicated by severe
